Births by legitimacy and sex

nCubes hold all the statistics presented by the Vision of
Britain system, and are defined as combinations of variables.
For example, the age-sex tables that appear in most census
reports are held as two-dimensional nCubes in which one
dimension is a variable categorising sex and the other
variable defines a set of age groups. nCubes can have many
dimensions, such as age by sex by occupation by cause of
death, or just one.
